Marry my bf or arrange marriage?

my bf of 6 years wants to marry me, but my parents are taking me back to our country in two weeks. They are being so diplomatic about us, sometime they are its good , but sometimes they say NO. My bf is trying his best to convince them but nothing is working. I don't want to elope either. My bf was married before , has 1 kid, but he loved me more then anything in the world. His ex-wife eloped with her new bf. But i don't want to do that, its bad reputation. If my parents take me to my country then everything will be over cause my bf is illigal in usa and can't go back. I am very scared. i know u guys can't really help me but still lookin for some advise...should i marry the person my parents choose for me ?
